" plate or nozzle and direct flame from the said plate or nozzle in fan-shaped formation as well as at vertical angles from said plate on to the walls of the fire box.

A further object is the provision of an oil burner in which the oil is caused to circulate vantages as well as in details of construction which will be hereinafter described, illustrated by the drawing and pointed out with particularity in the appended claims.

In the drawing:

Figure 1 is a top plan view of a burner in accordance with this invention.

Figure 2 is a substantially vertical longitudinal sectional View therethrough.

Figure 3 is a front elevation thereof.

Except for the spray plate my improved oil burner is made up of pipe sections and couplings for said sections;

Referring now to the drawing in detail, the numeral 1 designates a horizontally arranged pipe that comprises a plurality of short pipe sections connected together bya plug and by couplings as will hereinafter be described. The pipe 1 has screwed on one of its ends a T-coupling 8 and in this coupling there is screwed a plug 2. The plug has centrally screwed therethrough a steam conducting tube 4 which, of course, enters the pipe 1. The steam tube is connected to a suitable source of steam supply and, while 1931. Serial No. 580,937.

notshown by the drawing, the tube has its passage controlled by a hand operated valve,

I There is screwed in the lateral branch of the T-coupling 3 an oil inlet pipe 6, the said pipe being connected with a suitable source of oil supply and the oil from the supply may be heated.

1 Screwed in two ofthe confronting pipe sections 1 there is a cross coupling 7 and in one of the pipe sections connected with the coupling there is screwed one end of a plug 5. The tube i is threaded and screwed centrally through the plug 5 so that the tube is not in contact with the inner wall of the sections comprising the pipe 1.

The plug 5aflords a stop for oil which enters the pipe 1 to direct such oil through the lateral or transverse branches of the cross couplingi', but the oil before passing through such branches will be heated by the steam conducting tube 4. The lateral branches of the T-coupling 7 have screwed therein oppositely directed outwardly extending pipes 8 on whose outer 7 ends there are couplings for short and downwardly directed pipes 9. Horizontally arranged pipes 10 are screwed in the couplings and thus connected with the short pipes 9. The pipes 10 are of the same length and have screwed on their outer ends couplings to connect with the pipes 10 upstanding pipes 11. The upstanding pipes 11 have screwed 011 their upper ends couplings in which there are screwed inwardly extending short pipes 12 and these pipes 12 have their confronting ends screwed in a cross coupling13. The top or outwardly extending branch of thecoupling 13 is closedby a plug 14: while the depending branch has screwed therein a short depending pipe 15.

/ The lowerfend of the pipe 15 is'screwed in a T-coupling 16, and the lower end of the T-coupling 16 is closed by a screw plug 19, the same being screwed in and closing the upstanding branch of a coupling 18. The

coupling v18 is connected to the outer end of the pipe 1, and likewise is connected to a pipe extension 20 which isin reality an extension of thesaid pipe 1. The outer and threaded end-of thelpipe 20 is screwed in a round and threaded opening 23 onthe inner end of a burner spray plate 21. The spray plate has its bottom gradually widened from its said end 23 to its outer and open end and the sides are formed with upstanding flanges 22, while the rear and top of the plate 21 is formed with a downwardly arched lip 24 that enters the burner plate "between the sides 22 thereof.

In the outstanding or lateral branch of the coupling 16 there is screwed a pipe 17 and this pipe has screwed on its outer end a C- coupling to which is connected a depending oil outlet or nozzle pipe 18,

The plug 5 and the section of the pipe 1 adjacent thereto are connected together by a T-coupling 25 and in the lateral branch of this coupling 'there is screwed a pipe25.

The pipe25 is' connected with a sourceof hot air and while not show n by-the drawing,-t'he said pipe 25 has its passage controlled by a valve.

The device is positioned within a fire box or the like, and in operation, the oilp'assing through a part of the pipe 1 is heated bythe a pipe closed at its lower end-depending from the coupling and having a branch extending outwardly and then downwardly terminat ing in a nozzle immediately above said plate,

and an air pipe connected to the first named pipe intermediate the second plug and the end of the steam'pipe.

In testimony whereof I affix my signature.

'- MONROE BRITTAIN- hot steam conducting pipe 4 so that the oil,

while still in a heated state will pass through the pipes 9,10, 11, 15, 17 and the nozzle or outlet pipe 18, thesaid oil, of course,'being delivered onto the burner plate 21. Hot air from the pipe 25 maybe directed to the pipe 1 and its extension 20 to mix with the oil in the pan 21 to mix and further'heat the 7 oil in'the pan. The oil is ignited and when the flame has reached a suflicient temperature full flow of hot air and a 'full How of steam is directed into the panso that-the burning vapor in the pan will'be spread against the sides andend ofthe firebox. The heat thus created will be imparted to the oil conductor pipes so that afterthe fire is first [started the oil will be delivered in a vaporizedform ontothe burner pan 21. Obviously the flow of oil as well as the flow ofhot air and steam is regulated in the air 'p'assa'ge tothe burner plate and pan.

Obviously I do not wish to be restricted-to the precise details he-rein shown and described, therefore, hold myself entitled to makesuch changes therefrom as fairly fall within the scope of what I claim.

Havin'g de'scribed the invention, I claim: An oil burner comprising a horizontally extending pipe having oneend 'plug'ged'and an outwardly flared burner plate having side fla ng'es thereon connected to its otherend, s a1d "plate having a downwardlyextending lip partially closing the open end of the pipe,

a second plug withinthe pipe spaced from said first plug, a steam pipe extending in spaced relation within said pipe, and through 7 said plugs and terminating beyond said secend plug, an oil pipe communicating with said first pipe adjacent said first plug, laterally extending pipes connected to the first 'named pipe, one on each side, between said its
